Please implement something to teach players how to play

[Absurdity]

Again, I ask:

Please give me the names of other MMOs with which you are familiar who do this already.

I suspect the answer will be, as before, silence.

You can ask for 'mandatory', but unless you can show evidence that this is being done somewhere else (and, may I add, successfully) you're just talking through your own frustrations with players who are perhaps not as good at playing games as you are.

Most other MMOs solve this very simply, you get flamed, then you get kicked, then you get flamed some more. Since this obviously isn't a thing in this game due to it's ToS, and not exactly the most desirable solution either, we need other solutions that do not include other players constantly insulting you and kicking you from their parties until you learn.
